在Python中,您可以使用Pandas库来更改数据集中的字段类型。以下是一个示例代码,演示如何使用Pandas更改字段类型:
```python
import pandas as pd
# 创建数据集示例
data = {'Name': ['John', 'Sarah', 'Peter', 'Jessica'],
'Age': [28, 32, 25, 19],
'Gender': ['Male', 'Female', 'Male', 'Female']}
df = pd.DataFrame(data)
# 将Age字段的类型从整数改为浮点数
df['Age'] = df['Age'].astype(float)
# 输出结果
print(df)
```
在这个示例中,我们使用`astype()`函数将"Age"字段的数据类型从整数改为浮点数。您可以根据需要修改其他字段的数据类型。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
